OK. To clarify, however, I should say that what I meant for the fourth
choice is that the user could set the policy for themselves, choosing
once among the other alternatives. I do have some sort-of question-and-
answer stuff in my game, but I wouldn't want it used a lot - its just
too confusing to users and scenario writers.

Hmm. I could get used to that! (My current scenario happens to have
a room that comes equipped with a lot of rats, which aren't really
dangerous. Typing only one command to attack all of them would be handy!)

Sounds similar again. My server is now in C (initially in my own
language called "Draco"), and supports an internal language which the
scenario is written in. The server supplies a bunch of "builtin"
functions to help in parsing, however.

How does that work? Can normal players do it, or is it only available
to administrators?

OK, understood and agreed. I've done much the same, but it sounds like
I haven't gone anywhere near as far as you have. It was only recently
that I went and made sure that all NPC's had uniform 3-character
abbreviations. It's all been terribly ad-hoc. Do you have any kind
of human algorithm, etc. that allowed you to decide what abbreviations
to use? Similar for handing misspellings?
Lots of stuff on my system has been in this list before, but I'll mention
one relevant aspect here: I can add/remove any kind of vocabulary at
run-time, simply because the dictionary stuff is all created and
manipulated by "builtin" functions, which any player who has a
"wizard" character can access. However, the main dictionary is owned
by the "SysAdmin" character, so no-one else can directly modify it.
Much of my programming background has been the compilers universe, so
I've approached MUD-building from a programming language bias.
